游戏是你命你是我的命
[yóu xì shì nĭ mìng nĭ shì wŏ de mìng]
'The game is your life and you are my life.' Emphasizes two aspects: 1) Someone considers games as important as life 2) And also says this person means everything to him/her - highlighting dual dependencies on both gaming (possibly metaphorical play) and cherished relationships.
